She initially received adalimumab, but secondary loss of response occurred after 5 years. Her treatment was then switched to infliximab (IFX), which induced remission. Liver dysfunction was noted at 9 months after IFX initiation. Laboratory tests revealed positive antinuclear antibody (ANA), and liver biopsy demonstrated lymphoplasmacytic infiltration in the portal areas with interface hepatitis, indicating autoimmune hepatitis (AIH). After IFX discontinuation and ustekinumab initiation, alanine aminotransferase levels normalized within 4 months, whereas ANA status turned negative by 9 months.
